Demio said: That's a totally different situation, you're comparing apples to oranges.
One thing is an advanced Mac OS X user complaining that the File Manager sucks because he can't access /dev (a newbie shouldn't be fiddling with /dev). Besides, Mac OS X was made in such manner you won't ever need to access /dev.
A totally different thing is a linux newbie who probably needs help installing some stuff, or configuring some package (in linux you need access to all system directories).
One of my friends in question, who, asks me advice fairly often:
(A), in Ruby on Rails, _not_ using that silly tutorial, hand-coded (in Emacs nonetheless) his own fully-featured blogging platform. It took him about 6 hours' actual coding time including taking care of CSS issues, etc.
(B) Just finished writing this little gem
There are advanced users and noobs on _every_ platform, so denying either demographic the features they deem necessary to be productive is stupid at best..
Different OSes for different needs and different persons. Comparing them in this case is just borderline absurd.
Basic file management capabilities for both groups should be available regardless of platform.
Again, look at Windows - it might have a little warning message, but it will let you browse those sort of directories. Why can't Finder do the same?
